GAS BURNER FOR STARTING COAL FIRES.

Application filed January 14, 1928.

My invention relates to gas burner for starting coal fires, and aims to provide a novel and improved device of this character which may be conveniently placed in the ash pit of a coal stove or heater and supported on the bottom thereof so that the flames from the burners will ignite the coal and thus obviate the necessity of using wood for starting a fire.

Another object of the invention is the provision of a gas burner for starting fires, constructed in a manner for permitting the jets of flame to extend upwardly through the grate of a coal stove or heater in order that coal supported by said grate will be ignited, said burner being supported in position by an adjustable bar or lever pivoted to a base resting on the floor of the ash pit of the stove or heater, whereby said supporting bar may be adjusted for properly supporting the burner for use in stoves or heaters of different sizes.

It is also an object of the invention to provide a device of the above indicated character, which is simple and substantial in construction, which can be manufactured economically, and which will be thoroughly eflicient and practical in use.

With the foregoing and other objects in view, which will be apparent as the d escription proceeds, the inventionresides in the construction and arrangement of parts, as hereinafter described and. claimed, it being understood that changes can be made within the scope of what isclaimed, withoutdeparting from the spirit of the invention. The invention is illustrated in the accom" panying drawings, wherein:

showing a portion thereof in section,

Figure 3 1s a fragmentary cross section taken onlme 33 of Figure 2,

Figure 4 is a fragmentary cross sectiontaken on line 4-4 of Figure 1,. and

Referring to- Figure 1: of the drawings,

Serial No. 246,796.

cylindrical gas chamber 15 which may be constructed of the usual gas pipes provided with end caps 16 threadedthereon and intermediate the ends of the chamber is a mp 17 into which is threaded one end of a gas feed pipe 18 bent to permit the same to extend through the opening 14 to the burner when located in the ashpit, said feed pipe being bent at the points indicated by the numeral 19'. On the end of the gas feed pipe 18 opposite to that attached to the chamber 15 is a valve 20 for controlling said flow of gas to the chamber, and to this valve is attached a flexible tubing 21 connected tothe main supply of gas.

On the-upper side of the gas pipe forming the chamber 15' are a plnralityof openings 22 into which are threaded upwardly extending gas spray nozzles 23 which taper, towardstheir upperends to provide restricted openings through which the gas passes. Supported upon each of the nozzles 23- isa dome-shaped member 24 into which air is permitted to enter and mix with the gas; inorder to provide the desired flame. In the interiorof each of thedomeshaped members 24 is a collar 25 through the central opening 26 of which the nozzle 23' extends to support the dome-shaped member thereon, and said collar is provided concentrically with a plurality of openings 2? for permitting the air to pass therethrough. By referring to Figures '1 and 2 of the drawings it can be seen that the dome-shaped members 245 are supported upon the nozzles23 in a manner so that the lower edges thereof are spaced from the fuel chamber 15 so as not to interfere with the entrance of air into said dome-shaped members;

The upper portion of each dome-shaped member 24 is contracted to forma nipple 28? into which extends the upper end of the" nozzle- 23, and threaded on the upper end of-each nipple is a four-way coupling 29- to which the gas b1-1 rners 30 and 32 are connected, the burners 32 having intermediate pipe sections 31 by which they are spaced from the burners 30'. The upper ends of the burners 30' are on the same plane with the upper ends of the burners 3-2, as clearly shown in Figure 1 of the drawings. It istobe noted by referring to Figures 1 and 2 that the burners- 30 and: 32 time outwardly at their upper ends for increasin g'the' width of the flames. It is also to be noted that 34 pivotally, connected to the gas feed pipe 18 by means of a metal clip36 through the ears 35 of which the clamping bolt 37 passes and is extended at one side to receive the supporting bar or lever 34, the nut-39 of the bolt for clamping the clipto the feed pipe being interposed between the supporting bar and adjoining earof the clip, and on the outer end of said bolt is a clamping nut 40 having a handle 42 by which it is I turned to clamp the parts together. It can be seen that by loosening the clamping nut 40 the supporting bar or lever may be ad justed to various positions with relation to the gas feed pipe, and for the purpose of I manipulating this lever the outer end thereof is in the form of a handle 43. The sup porting bar is bent at an angle near its lower end and pivoted to a substantial base 45 adapted to rest on the bottom 13 of the ash pit 12. The base 15 has a pair of upwardly extending ears 46 between which the supporting bar or lever is connected thereto in such manner as to provide for adjustment. Through the ears 46 and the end 44 of the bar 34 area series of openings through which bolts 47 are passed for adjustably connecting the parts together. It can be seen that by. arranging the openings as clearly illustrated'in Figure 1 of the drawings the angle of the supporting bar 'or lever with relation to the base maybe varied so that the device may be used in connection with stoves and heaters ofdifferent v sizes.

In order to further aid in supporting the base burner against movement with relation to the supporting bar, a collar- 48 is fixed on the gas feed pipe 18 and has apair of depending ears through which a bolt, 50 extends for connecting thereto a prop 51 the lower end of which is adapted to be swung into engagement with teeth 52 on the upper edge of the supporting bar: By this arrangement it can be seen that the prop 51 may be swung to position for engaging the teeth 52 after the supporting bar has been adjusted on the base and will aid in supporting the structure against movement, and thus support the burners 30 and 32 in proper position with relation to the grateand coal in the stove or heater.

When it is desired to start a fire in a coal stove or heater, the device'is placed in the ash pit to rest on the bottom thereof, and in handling it for this purpose the outer end of the gas feed pipe 18 and the handle portion 43 of the bar 34 are grasped for swinging the bar 34 on its pivot to bring the base against the main fuel pipe 18 for passing the device through the opening 14 and on tothe floor 13 of the ash pit, the bars or lever being then manipulated to position the burners 30 and 32 between the bars of the grate 11. By tightening the clamping nut 40 movement of the bar 34 with relation to the pipe 18 is prevented, and swinging the prop 51 to position to engage the teeth 52, it can be seen that the device will be supported so that flames from the burners will ignite coal placed on the grate. When it is desired to use the device in connection with stoves or heaters having ash pits ofdiiferent heights, the base member 45 may be ad justed with relation to the bar 34 by removing the bolts 47 which connect the base member with the bar 34 and inserting the bolts through other holes in the ears 46 of the base member and holes in the end 44 of the bar 34. When the valve 20 is opened gas will flow through the feed pipe 18 to the chamber 15 and from the latter out through the nozzles 23 to the burners 30 and 32. As the gas passes from the nozzles 23, air entering the lower ends of the dome-shaped members 24 will be mixed therewith so as to provide a combustible mixture for igniting the coal supported on the grate.
